[lepido-dev] Problem with forms editor

[Ross Gardler <rgardler@xxxxxxxxxx>]

(is there a bug tracker for Lepido?)

I created a new XML file (empty) and tried to open it with the Forms 
editor. The following error is reported:

Problems occurred when invoking code from plug-in: 
"org.eclipse.ui.workbench".

org.eclipse.jface.util.Assert$AssertionFailedException: null argument;
	at org.eclipse.jface.util.Assert.isNotNull(Assert.java:149)
	at org.eclipse.jface.util.Assert.isNotNull(Assert.java:125)
	at 
org.eclipse.jface.viewers.StructuredViewer.assertElementsNotNull(StructuredViewer.java:545)
	at 
org.eclipse.jface.viewers.StructuredViewer.getRawChildren(StructuredViewer.java:849)

Right clicking in the editor does not provide a menu and trying to close 
the editor results in further errors (not reported as they are easily 
reproducable I hope).

If I then add a root element to the source view, i.e.

<fd:form
  xmlns:fd="http://apache.org/cocoon/forms/1.0#definition";>
</fd:form>

I can open the editor withut the above error, however, there is still no 
right click menu.

There are no problems if the file is populated with a complete form.
